Application filed January 30, 1907, Serial No. 354,808. Renewed June 22, 1908. Serial No. 439,862.

To all 'whom 'it may concern:

Be it known that I, CHARLES C. RITTEN- House, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Elevators, of which the following is a specifl. O

n of the building being broken away to illustrate the manner of placement in the building of the elevator. Fig. 2- is a transverse section taken on line 2--2 of Fig. 1. Fig. 3- is an elevation of the latch operating knob showing parts of the locking device in dotted lines. Fig. 4- is an elevation or' the operating crank clutch and ratchet mechanism. Fig. 5 is an edge view of the operating mechanism shown in Fig. 4. Fig. 6- is a view of the endless cable with the conveyer or engaging links in place thereon. Fig. 7- is an enlarged perspective view of one of the carriers. l

In the drawings 8 represents the walls of the building. In this case I have shown only the basement 9 and the first and second floors, as an illustration of a building having two floors will be ample to show the manner in which the elevator is installed in the building.

Disposed between the outer walls 10 and the plastering 11 of the rooms I have placed a passage way 20 for the passage up and down of a series of conveyers 12. These conveyers are preferably made of sheet iron having two compartments, an upper compartment 13 and a lower compartment 14, the upper compartment being open at the top and being water tight for the reception of garbage and waste material which may be dumped thereinto from the different rooms. In the lower compartment of the conveyer I have provided a side opening for the passage into the compartments o? the various articles which it may be desired to transfer from the basement to the various rooms and to receive liker articles from the rooms to be transferred to the basement. A separate conveyer is provided for each tier of rooms which are situated one above the other, and a separate carrier is provided for each room. v

The conveyor is detachably secured as which passes over a pulley 16 revolubly mounted above the top room, and passes around a revoluble pulley 17 in the basement. Each carrier is numbered with the same number as the room which it is intended to serve and is provided at its upper end with a supporting link 1S adapted for placement in the links 19 disposed on the endless cable. These links are spaced apart the distance ot one floor above the other and are so arranged that when the lower carrier is in place opposite the opening leading thereto from the lower room, the various carriers will be in register with the various openings leading from the respective rooms above. The carrier passage way 2O up and down in which the carriers move is provided with an opening 21 leading from the passage way 20 to each of the rooms. closed by the hinged Adoors 22 which open into the respective rooms at a convenient place therein as shown in Fig. 1.

To prevent throwing garbage, waste material or any substance into the passage way when the carrier is not in register with the opening leading from the room I have provided an interlocking device 23 which will engage the side of the carrier when the saine is in register with the opening leading from the passage way and crowd the engaging spring 24 inwardly carrying the locking bolt 25 which is secured thereon until the opening 26 in the bolt registers with the locking bolt 27, permitting the knob 28 on the door 22 to be rotated and retract the locking bolt 29 when the door 22 can be opened. Thus it will be seen that the locking bolt 29 cannot be withdrawn except when the carrier is in place in the passage way.

elevator it will be found convenient to establish certain hours of the day in which the janitor can remove the various packages from the package chamber 14 in the various l receptacles and any garbage in the waste rehereinafter explained, to an endless cable 15 In a building provided with my improved l These passage ways are ceptacle '13 by pennitting the vvarious ycargoods may b'e delivered from the basement fiers to 'descend from their positions in'n register with the doors leading to them in the various apartments. To lo'wer 'the receptacles I have provided the ratchet mechanism shown in Figs. 4 and 5 and which will be located in the basement of the building. Pulley 17 is provided with ratchet wheel 38 rigidly afiixed to its side. Dog 39 is mounted in bearings 40 so as to engage the teeth of ratchet wheel 38 to prevent the' downward movement of the receptacle. Pulley 17 is mounted in bearings 41 which are adjustable vertically by means of slotted bolt holes as shown in Fig. 5. Bearings 40 for dog 39 are made integral with bearings 41 so that dog 39 may be always in the same position relatively to ratchet wheel 38. Hand brake 42 is mounted on a post 43 at the side of pulley 17 so as to bear against the rope at a point above the pulleyl and thereby prevent its upward movement. Rope 15 bears against post 44 at this point so as to furnish a solid backing for the action of the brake.

Y lVhen it is desired to lower the receptacle, dog 39 is thrown upward out of engagement with ratchet 38 and hand brake 42 is pulled upwardly to partially release the rope. The receptacles will then descend more or less slowly as less or more pressure is exerted by thehand brake upon the rope. When the receptacle from the first floor has reached the basement the hand brake is released by the operator and the rope is then held tightly until such receptacle is removed from the cable. To remove a receptacle from the cable it is necessary to tip such receptacle sidewi-se until link 18 is in resister with the hole in lin-k 19, as link 18 is inclined somewhat to the vertical. In this manner I provide a means whereby it is impossible to remove the receptacles from the cable while they are in the passage way. The cable is then again slowly released until the receptacle from the second story has reached the basement; thisY operation is repeated until all thelreceptacles have been removed from the cab e.

Then all the receptacles have been cleaned and if necessarv disinfected. the one belonging to the top Hoor is then hung on the uppermost link in the cable and hoisted until the next link in the cable comes into a position whereV it is easy to attach the corresponding receptacle. During the hoisting process dog 39 is in engagement with ratchet wheel 38, and holds wheel 17 and the cable against any downward movement of the y receptacles. By these means I have provided a very convenient and efficient means for` removing garbage and waste material from the several rooms and .apartments of a at,l

.and have also provided al means wherebyl atv any stated hour during the day.

Having described my invention what I claim as-new and desire 'to secure by Letters Patent is 1^. In a flat elevator, a shaft for the passage up and down therein of receptacles on one side of la cable, doors in the wall of 'said shaft leading from each floor of the flat to the shaft, a cable in said shaft, links aiiixed to one side thereof at positions corresponding to the positions of said doors, receptacles on one side of said cable, said receptacles having means whereby they may be detachably secured to said links, and means to operate the cable up and down.

2. In a flatV elevator, a shaft, doors in the wall of said shaft on each iioor of the flat, a

cable in said shaft, links aiiixed to said cable' at positions corresponding to the positions of said doors, receptacles, said receptacles having means whereby they may be detachably secured to said links, locking means on said doors, whereby said doors may only be opened when said receptacles are'opposite said doors, and means to operatefthe cable.

3. In an elevator, a shaft, a movable endless cable therein, receptacles d'etachably secured on one half of thecable and adapted to register with the doors lead-ing into the shaft when the cable isstationary or in its normal position, doors leading into said shaft, locks on said doors, and means operated by said receptacle to unlock said locks when the receptacle is in register with the door leading into the shaft. Y Y

4. An elevator comprising a shaft in the wall of a building, an endless cable arranged to move up and down therein, detachable receptacles on one side of' said cable spaced apart to register with the different rooms in the building, openings above the floors-leading from the rooms to the shaft, closures on said openings, means to lock these closures at all times except when the receptacles are in register with the openings, and means to operate said cable` up and. down.

5. In a flat elevator of the class described, a cable, a receptacle, and means to attach the receptacle to the cable comprising. a link affixed to the cable and a supporting 4link on the receptacle adapted to engage with' the link on the cable so as to prevent the removal of the receptacle from the cable While the receptacle is in the elevator shaft.

In witness that I claimA the foregoing I have hereunto subscribed my name this 23rd day of January, 1907. p Y Y Y n CHARLES C. RITTEN HOUSE.
